Draft Classes, Rosters, MyLeague/GM not saving

Whenever I try to save draft classes, rosters or save myleague files it does not save and I lose everything I create for both 2k21 and 2k20. Does anyone know how I can fix this issue without having to lose player dna's and players ive created?

I have the same problem with nba 2k20 last year and i delete a few save games, rosters and it work for me. Dont forget a backup.
